Coconut oil is actually semi-solid at room temperature and there is no need to melt it to mix this up. It blends easily. I found this recipe at My Frugal Adventures, where Charlene mentions that you can add more sugar if you'd like more exfoliation. I plan on trying other scents too.
Homemade Coconut Lime Sugar Scrub
¼ c. coconut oil
1 c. sugar
2 large limes or 3 small limes (3-4 T. lime juice)
3 T. lime zest
Using a grater or microplane, grate 3 tablespoons of lime zest from the lime. Once you have your lime zest, cut the lime in half and juice it for 3-4 tablespoons of lime juice. In a medium size bowl, combine the coconut oil, sugar, lime juice and lime zest and mix well.
